SPECIFICATION forming part of Letters Patent No. 509,136, dated November 21, 1893.

Applicationfiled January 3, 1893. Serial No. 457,021- (No model.)

To all whom it may concern:

Be it known that I, GEORGE G. MOMURTRY, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Sheet-Metal Packages,of which improvements the following is a specification.

The invention described herein relates to certain improvements for securing metal sheets, especially such as have a protecting coating, in packs for shipment or storage.

It has heretofore been the practice to arrange a suitable number of sheets in a pack or pile, pass a flat metal strip across one side of the pack or pile, and then bend the ends of the strips around the edges of the pack or pile and down onto the opposite side of the pack. In order that the sheets maybe clamped tightly together, the ends of the strips are hammered down onto the side of the pack. It frequently happens that the edges of these strips are forced through the protecting coating, thereby spoiling the sheet; and, further, as the bent ends of the strip are hammered down so tightly and are so stiff, it is necessary to use an edged tool as a cold chisel, to bend the end back to release the sheet, and in forcing the tool under the ends of the clamping strip the coating is cut and stripped from the plate.

The object of the present invention is to protect the surface of the sheet from injury in either of the ways described, and the invention consists in the combination and arrangement substantially as hereinafter described and claimed.

In the accompanying drawings forming a part of the specification, Figure 1 is a perspective view of a sheet metal package having my improved fastening applied thereto, and Fig. 2. is a transverse section through one of the clamping strips.

In the practice of my invention, the sheets 1 in any desired number, are arranged in a pack or pile in the usual manner. At suitable points along the edges of the pack or pile are placed the protecting pieces 2,which fit around the edges of the pile and extend over the upper and lower faces of the pile or pack. The fastening strips 3 are then passed under the pack in line with the protecting pieces, and the ends thereof bent around the edges of the pile or pack and forced tightly down upon the protecting pieces on top of the pile or pack, thereby clamping the sheets together. These protecting pieces, which are made of any suitable material preferably thin sheet metal, so that they can be easily removed without the aid of a sharp tool, have such a width and length as to extend beyond the sides and ends of the fastening strips 3, as shown in Figs. 1 and 2, and extend around the edges of the pack or pile, thereby preventing any contact of the strip with such portions of the pile as would be liable to injury in applying or removing the fastening strip; and, further, as the protecting piece extends beyond the sides and ends of the strip, the tool employed in bending up the ends of the strip can be slid in between the strip and protecting piece and not come in contact with the surfaces of the sheet.

I claim herein as my invention- 1. The combination of a pack or pile of sheet metal, a fastening strip passing across one side of the pack and having its ends bent around the edges and down onto the opposite side of the pack or pile and a flexible metallic protecting piece folded around the edges of the pack or pile and interposed between the pack or pile and the fastening strip, substantiallyas set forth.

2. The combination of a pack or pile of sheet metal, a fastening strip passing across one side of the pack and having its ends bent around the edges and down onto the opposite side of the pack or pile and a flexible metallic protecting piece folded around the edges of the pack and interposed between the fastening strip and the pack and extending beyond the sides and ends of the fastening strip, substantially as set forth.

In testimony whereof I have hereunto set my hand.

GEORGE G. MOMURTRY.
